Our Lady of Mantara is a Melkite Greek Catholic Marian shrine in Maghdouché, Lebanon, discovered on 8 September 1721 by a young shepherd. The grotto, which according to a legend dates to ancient times, was subsequently cared after by Monsignor Eftemios Saïfi, Melkite Catholic bishop of the Melkite Greek Catholic Archeparchy of Sidon. The shrine consists of a tower crowned with the statue of the Virgin and Child, a cathedral, a cemetery and a sacred cave believed to be the one where the Virgin Mary rested while she waited for Jesus while he was in Tyre and Sidon. Since its discovery, it has been steadily visited by families particularly each year on the occasion of the feast of the Nativity of Mary on 8 September.

A shrine to the Virgin Mary, or Marian shrine, is a shrine marking an apparition or other miracle ascribed to the Blessed Virgin Mary, or a site on which is centered a historically strong Marian devotion. Such locales are often the destinations of Christian pilgrimages.
